FIG. 1 shows a sectional view through a schematic illustration of a first embodiment of an atomizer 101, wherein atomizer nozzles 102a to 102h are in a rest position R102. FIG. 2 shows the atomizer 101 shown in FIG. 1 with atomizing nozzles 102a to 102h which are in a working position A102. Finally, FIG. 3 shows a view of the atomizer 101 shown in FIG. 1 as a detail

in the area of its atomizer nozzles 102a to 102h.

The electrostatic atomizer 101 is for a

electrostatic atomization of liquids 103 is provided. Here, among liquids, in particular cosmetics in a broader sense, but e.g. also understood paints and varnishes. The atomizer 101 comprises a housing 104, an electrical energy source 105, an activating means 106, which is designed as an electrical switch 107, a

Control electronics 108, a high voltage source 109, a liquid tank 110, a conveyor 111 and the aforementioned spray nozzles 102a to 102h. The conveying device 111 is between the liquid stank 110 and the

Nebulizer nozzles 102a to 102h arranged. Here, the conveying device 111 is connected by a first line 112 to the liquid tank 110 and here is the

Conveying device 111 connected by a second conduit 113 with the atomizer nozzles 102a to 102h, so that the

In the spraying operation, the conveying device 111 sucks liquid 103 out of the liquid tank 110 and delivers it to the atomizing nozzles 102a to 102h. The line 112 and 113 is shown here as a one-piece continuous hose. For clarity, only one hose to the nozzle array of the atomizer nozzles is shown. The atomizer nozzles but can through several hoses, in particular one hose per

Nebulizer nozzle or even a hose for a group of some nebulizer nozzles are supplied. In the case of

Use of multiple hoses is also a multi-hose pump provided which, for example, by a wider rotor a plurality of hoses, arranged in the manner of a Flat bands (similar to a ribbon cable) can pump parallel.

Namely, the conveyor 111 is a pump 114

Positive displacement pump, in particular peristaltic pump in the design of a suction pump 115 is formed. The suction pump 115 is formed as a peristaltic pump 116 and designed so that a arranged between the first conduit 112 and the second conduit 113 conveying hose 117 in the pumping operation of arranged on a rotor 116a rollers 116b, 116c alternately rolling deforms and in this case is completely depressed, as this is shown in Figure 1 in the region of the roller 116b.

The atomizer 101 comprises a switching device 118, by means of which a direction of rotation of the rotor 116a of the

Peristaltic pump 116 is switchable such that the

Hose pump between a conveying operation in which the rotor 116a rotates in a direction of rotation w and a

Return feed operation, in which the rotor 116a rotates in an opposite direction of rotation w ^A , changes. Through a short-term return operation, it is possible to

avoid unwanted leakage of liquid 103 after spraying. In this case, it is provided to avoid a reclamation of the liquid 103 into the liquid tank 110. This is achieved in that the first conduit 112, which like the delivery hose 117 is elastically stretchable, is slightly stretched by the return feed to increase its internal volume and the liquid tank 110 remains closed by a non-illustrated check valve. In order to ensure a large storage volume of the first line for a recovery, it is provided to form the first line at least 1.5 and in particular twice as long as for connecting the liquid tank with the

Conveying device is required. Alternatively, it is also intended to use small amounts of liquid

Return return operation via a switch or a corresponding valve in a disposal tank to direct. This makes it possible, the second line 113 largely completely empty.

The conveying device 101 and the high voltage source 109 are via the activating means 106, which by the

electrical button 107 is formed, activated. The button can also be designed as an electronic button, in particular as a capacitive sensor, as a reed contact or as a Hall sensor. In the case of the activating means, an actuating element 107a of the push-button 107 is electrically conductive and as the opposite pole to the atomizing nozzles 102a to 102b

is trained. After the button 107 has to be pressed permanently for spraying, in this way a good connection of the user to the reference potential of the spraying device 101 is ensured.

The atomizer 101 includes an acoustic signal generator 119, which is connected to the control electronics 108.

As a result, the user can be informed acoustically about a correct or incorrect use of the atomizer 101 and the handling of the atomizer 101 can thus be trained and optimized. Additionally or cumulatively, a vibrating signal generator is provided, which is always active at a certain frequency when the atomizer sprays. By vibrating with a different frequency, further information can be conveyed to the user.

The atomizer 101 comprises a connection means 120, the liquid tank 110 being detachably connected to the connection means 120 via a self-closing valve 121.

As a result, a coupling and decoupling of the liquid tank 110 with simple hand movements is possible and thereby an unwanted leakage of the liquid tank 110 is effectively prevented. The liquid tank 110 is designed as a self-collapsing tank and for this purpose comprises a foil bag 110a. Such liquid tanks can be inexpensively

produce. Furthermore, the level is such Liquid tanks by a visual inspection with appropriate use of transparent components and / or appropriate positioning of openings easily detectable. The first line 112, the second line 113 and the

Delivery hose 117 are integrally formed and formed by a connecting tube 122. As a result, the number of joints is reduced, so that the danger a

Training of deposits is reduced.

Between the liquid tank 110 and the control electronics 108, means 123 for identifying the liquid tank 110 are included, wherein these means 123 are designed as detection means which detect information printed on the liquid tank or stored on the liquid tank and corresponding to the control electronics

Forward information. This is the

Control electronics 108 able to adjust various parameters such as height of the high voltage, power of the pump, etc. on the liquid to be sprayed 103. The

Identification means can be used in particular as RFID

Markings be formed, which of the

Control electronics 108 can be read in the atomizer. It is particularly preferred that the control electronics 108 can also describe the markings, in particular the RFID markings. Thereby, e.g. a date is noted on which a liquid tank was used for the first time or which amount has already been taken. The atomizer 101 comprises 8 atomizing nozzles 102a to 102h, which are arranged in an annular manner (see FIG. 3). As a result, body surfaces of a few square centimeters can be sprayed so that rapid spray progress is ensured.

The atomizing nozzles 102a to 102h form a nozzle array 124 (see FIG. 3), with the nozzle array 124 acting as a grid 125 with grid lines intersecting at grid points 126a to 126i 127a to 127f, wherein it is provided in particular that the atomizer nozzles 102a to 102h

Form grid points of parallel grid lines. By such a regular geometric arrangement, a uniform application of the liquid can be achieved.

It can again be seen from FIGS. 1 and 2 that the housing 101 has a gripping portion 128, a head portion 129 and an intermediate portion between the gripping portion 128 and the gripping portion 128

Head portion 129 disposed central portion 130, wherein the atomizing nozzles 102a to 102h are arranged in the head portion 129, wherein the conveyor 111 is disposed between the liquid tank 110 and the atomizing nozzles 102a to 102h.

As can be seen from FIG. 1, it is also provided that the atomizer 101 comprises a heating device 140 and a cooling device 141, the liquid 103 being heated before it leaves the atomizing nozzles 102a to 102h to reach a predetermined temperature and / or viscosity or can be cooled.

Alternatively, it is also provided to arrange the liquid tank between the conveying device and the atomizer nozzles.

Figures 4a and 4b show a second embodiment of an atomizer. In the atomizer 201, a housing 204 is made telescopic, so that a distance between a head portion 229 and a handle portion 228 is variable (see Figures 4a and 4b). This makes it easier for a user, for example, the spraying of the feet.

Figures 5a and 5b show a third embodiment of an atomizer. In the atomizer 301 are a 329th

Head portion and a handle portion 328 against each other rotatable. In FIG. 5 a, the nebulizer 301 is shown without twisting, and in FIG. 5 b is the head section 329 EP2018 / 060117

- 10 - relative to the handle portion 328, on which also an unillustrated activating means is arranged, rotated by 90 ° about a vertical axis H301 to the right. By such twistability is e.g. the spraying of the shoulders

simplified.

Figures 6a and 6b show a fourth embodiment of an atomizer. The atomizer 401 has a

Handle portion 428, which is bent relative to a head portion 429 thereby, that the atomizer 401 a

Includes articulated joint. This is e.g. the spraying of the soles of the feet or the back is simplified.

Of course, it is also provided to combine the three designs shown in Figures 4a to 6a and thus to combine their advantages, so that an atomizer is formed, which is optimally suitable for self-application.

In the atomizers 201, 301 and 401, it is intended to form these with a length L201 or L301 or L401 of about 10 cm to 25 cm, wherein the length L204 in the telescopic atomizer 201 indicates the length which this in the

pushed together state (see Figure 4a). According to an embodiment variant, not shown, it is also provided that the atomizer in addition to the first liquid tank comprises a second liquid tank, that the atomizer in addition to the first conveying device comprises a second conveying device and that between the

Conveyors and the atomizer nozzles one

Mixing device is interposed. In this way, different liquids can be mixed. By a different control of the conveyors

With regard to the speed of the rotors, the two liquids can also be different in terms of quantity

Mixing composition, so that, for example, the proportion of care substances can be increased or decreased. Another variant, not shown, provides that the atomizer a heater and / or a

Cooling device comprises, wherein the liquid before the

Exit from the at least one atomizer nozzle for

Achieving a given temperature and / or viscosity is heated or cooled. This can be at

different ambient conditions largely

achieve comparable spray results. It is also intended to operate the atomizer so that the conveying device for conveying the liquid both in the feed direction, so for the transport of liquid from

Liquid tank towards the atomizer nozzles, as well as in

Retraction, ie for the transport of liquid from the atomizer nozzle is operated in the direction of the liquid tank. By such a bidirectional operation of

Conveyor brings this the added benefit that a leakage of liquid can be reliably avoided after spraying.

In the case of the atomizer 101 shown in FIGS. 1 to 3, as already mentioned, there is a changeover between a

Resting position R102 and working position A102 possible.

Here, the atomizing nozzles 102a to 102h are in the

Rest position R102 (see Figure 1) are positioned in an interior 131 of the housing 104 and protrude in the

Working position A102 at least in sections over an outer side 132 of the housing 104 addition (see Figure 2). For this purpose, the housing 104 and the atomizer nozzles 102a to 102h are mutually movable, the atomizer nozzles 102a to 102h are arranged on a base plate 133 and are moved together with this of a lifting cylinder 134 relative to the housing 104. By such mobility, the atomizer nozzles 102a to 102h when not in use
